Modern Optics

Optics, a branch of physics, focuses on the study of the properties and behaviour of light, including its interactions with matter and the design of instruments to detect it. This field is also concerned with exploring electromagnetic waves, such as ultraviolet light, infrared light, microwaves, and radio waves. Optics is traditionally categorized into classical optics, physical optics, and modern optics. Classical optics considers light as an electromagnetic wave traveling in straight lines. Physical optics examines the wave nature of light, addressing phenomena such as superposition, dispersion, and interference. Modern optics explores advanced devices and technologies, including lasers, photomultipliers, image sensors, charge-coupled devices, and quantum electronics. This book elucidates the concepts and innovative models around prospective developments with respect to optics. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. For someone with an interest and eye for detail, this book covers the most significant topics in the field of modern optics.
